63 dnl Macro to add for using GNU gettext.
65 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
66 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
67 dnl default (if it is not specified or empty) is 'no-libtool'.
68 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
69 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
70 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
71 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
72 dnl depending on --{enable,disable}-{shared,static} and on the presence of
73 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
74 dnl $(top_builddir)/intl/libintl.a will be created.
75 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
76 dnl implementations (in libc or libintl) without the ngettext() function
77 dnl will be ignored. If NEEDSYMBOL is specified and is
78 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
79 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
80 dnl INTLDIR is used to find the intl libraries. If empty,
81 dnl the value `$(top_builddir)/intl/' is used.
82 dnl
83 dnl The result of the configuration is one of three cases:
84 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
85 dnl and used.
86 dnl Catalog format: GNU --> install in $(datadir)
87 dnl Catalog extension: .mo after installation, .gmo in source tree
88 dnl 2) GNU gettext has been found in the system's C library.
89 dnl Catalog format: GNU --> install in $(datadir)
90 dnl Catalog extension: .mo after installation, .gmo in source tree
91 dnl 3) No internationalization, always use English msgid.
92 dnl Catalog format: none
93 dnl Catalog extension: none
94 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
95 dnl The use of .gmo is historical (it was needed to avoid overwriting the
96 dnl GNU format catalogs when building on a platform with an X/Open gettext),
97 dnl but we keep it in order not to force irrelevant filename changes on the
98 dnl maintainers.

2439 dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
2440 dnl programs that really need multithread functionality. The difference
2441 dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
2442 dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
2443 dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for

3918 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
3919 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
3920 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
3921 #
3922 # Of course, Automake must honor this variable whenever it calls a
3923 # tool from the auxiliary directory. The problem is that $srcdir (and
3924 # therefore $ac_aux_dir as well) can be either absolute or relative,
3925 # depending on how configure is run. This is pretty annoying, since
3926 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
3927 # source directory, any form will work fine, but in subdirectories a
3928 # relative path needs to be adjusted first.
3929 #
3930 # $ac_aux_dir/missing
3931 # fails when called from a subdirectory if $ac_aux_dir is relative
3932 # $top_srcdir/$ac_aux_dir/missing
3933 # fails if $ac_aux_dir is absolute,
3934 # fails when called from a subdirectory in a VPATH build with
3935 # a relative $ac_aux_dir
3936 #
3937 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
3938 # are both prefixed by $srcdir. In an in-source build this is usually
3939 # harmless because $srcdir is `.', but things will broke when you
3940 # start a VPATH build or use an absolute $srcdir.
3941 #
3942 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
3943 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
3944 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
3945 # and then we would define $MISSING as
3946 # MISSING="\${SHELL} $am_aux_dir/missing"
3947 # This will work as long as MISSING is not called from configure, because
3948 # unfortunately $(top_srcdir) has no meaning in configure.
3949 # However there are other variables, like CC, which are often used in
3950 # configure, and could therefore not use this "fixed" $ac_aux_dir.
3951 #
3952 # Another solution, used here, is to always expand $ac_aux_dir to an
3953 # absolute PATH. The drawback is that using absolute paths prevent a
